Support for Consumer Groups, Statistical Functions, and Locale

The Stream Analytics team is pleased to announce several new features available today.

Support for Event Hub Consumer Groups

Last month's update added REST API support for specifying Consumer Groups on Event Hub inputs and this is now surfaced in the Azure Management Portal. Consumer groups enable multiple consuming applications to each have a separate view of the event stream, and to read the stream independently at its own pace and with its own offsets. When consumer group is not specified, Stream Analytics jobs will use the Default Consumer Group to ingest data from the Event Hub.  Note that associating your Stream Analytics job with a specific Consumer Group is the way to work around the 5 receiver maximum limitation that many customers have reached out to us about on the forum.

Support for Statistical Functions

Based on customer requests, we have extended the built-in functions for the Azure Stream Analytics Query Language to include the statistical functions VAR, VARP, STDEV, and STDEVP.

Locale Support

You can now specify the internationalization preference for a Stream Analytics job, which affects how the job will parse, compare, and sort incoming data. This setting is available on the Configure tab of a job.

Globalization and Localization

The Stream Analytics extension in the Azure Management Portal is now available in the following 11 languages: Simplified Chinese, Traditional Chinese, English, French, German, Italian, Japanese, Korean, Portuguese (Brazil), Russian, Spanish.


Thank you for your continued feedback on Stream Analytics. We look forward to hearing from you on the Stream Analytics Forum and Azure Feedback Forum. Stay tuned for more product updates coming soon!

    I am still getting 400 error if I would add /public consumer group to the path.  Without it, it works fine.  Could you help on this?

    request.protocol_override = "https"

    request.path = "/ioteventhub/publishers/public/" + partition + "/messages?api-version=2015-02"

  2. Hi Patrick, sorry to hear that you're running into this issue.  Would you provide detailed steps to reproduce the behavior on our team forum?…/home
